A glycerin drop of mass 10^(-3) g with charge equal to 2e is balanced in an external electric field. Calculate the strength of electric field, if the field is sufficient enough to hold the drop.

Two charges of +5nC and -2nC are placed at points (5cm, 0, 0) and (23cm, 0, 0) in a region of space where there is no other external electric field. Calculate potential energy of this charge system.

An electron accelerated by a potential difference V= 3 volt first enters into a uniform electric field of a parallel plate capacitor whose plates extend over a length l= 6 cm in the direction of initial velocity. The electric field is normal to the direction of initial velocity and its strength varies with time as E= alpha t, where alpha= 3600 V m^-1 s^-1. Then the electron enters into a uniform magnetic field of induction B = pi xx 10^-9 T. Direction of magnetic field is same as that of the electric field. Calculate pitch of helical path traced by the electron in the magnetic field. (Mass of electron, m = 9 xx 10^-31 kg )

Which of the following statements is//are correct? a. Electric field calculated by Gauss law is the field due to only those charges which are enclosed inside the Gaussian surface. b. Gauss law is applicable only when there is a symmetrical distribution of charge. c. Electric flux through a closed surface is equal to total flux due to all the charges enclosed within that surface only.

Mark the correct options: Gauss's law is valid only for uniform charge distributions. Gauss's law is valid only for charges placed in vacuum. The electric field calculated by Gauss's law is the field due to all the charges. The flux of the electric field through a closed surface due to all the charges is equal to the flux due to the charges enclosed by the surface.

(a) Derive an expression for the torque experienced by an electric dipole kept in a uniform electric field. (b) Calculate the work done to dissociate the system of three charges placed on the vertices of a triangle as shown. Here q= 1.6 xx 10^(-10)C .
